TO ALL WHOM IT MAY CONCERN:

Be it known that we, J n'n'oivin B. BEALL and BENJAMIN GRIM, of Westervi lle, Franklin county, State-of Ohio, have invented a new and Improved Road Scraper; and We do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanyingdrawings, making apart of thisspe'cification, in which Figure l is a bottom view of a reversible scraper having our improvement applied to it. -Figure 2 is a similarv view showing the scraper in the actof turning over.

desired.

Figure 4 is a front or edge view of the same device, Similar letters of reference indicate corresponding parts -in the several figures. This inventionrelates to an improvement on revolving or reversible scrapers which ar1designed for 'levelling :roads, and other purposes. It consists in providing the frame, to which the scraper is pivoted with a device, by means of which the attendant, having hold of the handles of the scraper, can release the latter, from a latch, at pleasure, without removing either hand from said handles, or stopping the horse drawing the machine, as will be endof rod g, in place upon the spnr-wheel h.

hereinafter described, l

. To enable others skilled in the art, to understand this invention we will describe its construction and operation. I l V V i In the accompanying=drawings, represents a well known revolving or reversible scraper which is, pivoted to the ends of two handles, B B, in such manner that when one part of the scraper is filled the other part can be 'brougnt into workmg position byallowing'th'e scraper to turn over. This scraper is-pivoted by a transverse Figure 3 isfan enlarged bottom view of the device for holding the scraper in position and releasing it when rod, a, to the ends of the handles; and the extremities of this rod project far enough from the sides of the scraper to receive theeyes, which are formed on the rear ends of a hitching how, 0, to which a horse is attached, for drawing the scrapen, The arms orhandles, B B, are connected together hear their curved hand pieces, 6 b by means of a transverse cross-bar, D, to the middle of which, and on its upper surface a vibrating latch c, is pivoted, as shown in the several figiires of the drawings. The forward end of this'latch projects beyond the front edge of the cross-bar, D, far enough to catch over that edge of the scraper'which is uppermost, and out-ofliaperation,

and prevent/the scraper from turning over and discharging its load when in operation. To prevent that edge ofthe scraper which is upperfmostfand which is arrested by the latch c, from dropping down a spring latch, d, is used, which is applied to the bottom of the cross-bar D, and so constructed as to be self-acting. The two catches a and d, will hold the scraper in 'position for operation whicheirenedge is uppermost; To the rear part of the late... a, a transverse rod, g, is pivoted, which has rack-teeth formed-omits lower edge near its outer. end. The teeth of this rod engage with the teeth oi a spur-wheel, h, which is secured fast to a tube or sleeve, -j, thatis allowed to turn freely on the end of arm B. This sleeve j, receivesinto its rear end the curved handle or handpiece 6, so that by turning' this hand-piece in one direction the latch, a, will rele'asc the scraper, and'by turning it back again this latch will be, brought in a position. forcatching and arresting the scraper. The two plates, in, and k, prevent the hand-piece from being detached from arm B, and also serve as guides for keeping the toothed Believing ourselves the first to have invented vany means which will admit of the release of the scraper, so that it can be revolved or reversed'at pleasure, without requiring the attendant to remove his hands from the handles, we do not confine ourselves to the precise construction and arrangement of parts herein described and shownfor cfi'ecting this object, as-other analogous means may be'employed. 1

Having described our invention, what weclaim as new, and desire to secure by Letters Patent,. is-

1. In a reversible road scraper, connecting the latch, c, to a loosely turning handle-piece b, by means i which will allow of the movement of said latch by turning the handle-piece, without removing the hands from either of the handles, substantially as described;

2. The combination of a vibrating-latch; c, a sliding spring-latch'd, and a movable hand-piece, 6, substantially as described, with a reversible scraper.
